The diglyceryl phthalate epoxy resin contains a benzene ring in its molecular structure, and its molecular weight is small. In addition to the generality of epoxy resins, it also has the advantages of low viscosity, moderate reactivity, high adhesion, good compatibility, excellent electrical insulation and ultra-low temperature, and good weather resistance. It has good adhesion with carbon fiber, and it is suitable to make carbon fiber composite material. Based on this background, this article mainly focuses on the seat art design, and uses the wrapping method to analyze the preparation of the carbon fiber composite resin matrix. The optimal reaction conditions are determined by changing the reaction during the preparation of the thermoplastic resin matrix. / PA = 1.9, esterification time 120min, cyclization time 70min, reaction temperature 110 °C, amount of promoter water 6g, concentration of cyclizing agent sodium hydroxide solution 30%. The resin synthesized in this case is a light-yellow transparent liquid with an epoxy value of 0.51 (mol / 100g).
